Anthropogenic nutrient loading affects both individual species and the trophic structure of river fish communities

Frontiers in Ecology and Evolution, 2023
Although the concept of trophic interactions has been used for a long time, there are still considerable gaps in our understanding of the effect of various environmental factors on trophic interactions within river fish assemblages.

Is the relationship between body size and trophic niche position time-invariant in a predatory fish? First stable isotope evidence. [PDF]

PLoS ONE, 2010
Characterizing relationships between individual body size and trophic niche position is essential for understanding how population and food-web dynamics are mediated by size-dependent trophic interactions.

The relationship between niche breadth and geographic range size in African Horseshoe bats (Rhinolophidae, Chiroptera) [PDF]

, 2011
According to Brown's hypothesis, generalists have high niche breadth and can tolerate a wide variety of environmental conditions resulting in large geographic range sizes. Conversely, specialists have low niche breadth and small range sizes.

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Influence of seascape spatial pattern on the trophic niche of an omnivorous fish

Ecosphere, 2022
Habitat fragmentation of submerged aquatic vegetation (SAV) transforms the spatial pattern of seascapes by changing both the total area and spatial configuration of the habitat patches.

Contrasting evidence of phylogenetic trophic niche conservatism in mammals worldwide [PDF]

, 2016
Aim Phylogenetic niche conservatism (PNC), a pattern of closely related species retaining ancestral niche-related traits over evolutionary time, is well documented for abiotic (Grinellian) dimensions of the ecological niche.

Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Linking Phylogeny and Morphology to Resource Assimilation Within Aquatic Assemblages

Ecology and Evolution
Niche partitioning promotes species coexistence. Yet, it remains unclear how phylogeny and morphology influence the trophic niches of closely related aquatic species with shared feeding modes.

Seasonal Trophic Niche Shift and Cascading Effect of a Generalist Predator Fish

, 2012
Few studies have examined how foraging niche shift of a predator over time cascade down to local prey communities. Here we examine patterns of temporal foraging niche shifts of a generalist predator (yellow catfish, Pelteobagrus fulvidraco) and the ...
